Types of medical gas systems
There are two basic types of medical gas systems, namely:
unilateral system:
It is a system that is the pressure to reduce medical gas pressure required at the exits and the beginning of the main station for the supply of various gases.
binary system:
It is a system that reduce pressure medical gas which is in two phases the first phase takes place in the main station to the top of the exits at the desired pressure and then pressure is then pressure reduction phase
Components of medical gas system
Medical gas systems consist of the following elements:
sources of supply plants or various medical gases.
Distributed gas piping network.
exits medical gases.
monitoring and warning system.
sources of supply stations and various medical gases
Are sources that supply piping system various medical gases and this element is also divided into several elements are as follows:
• the supply of medical gas cylinders through the station.
• the supply of compressed air station through the air compressors.
• suction through suction pumps station.
First: medical gas supply station through the cylinder
It is designed to extend hospital departments and medical gases (oxygen, nitrous oxide, carbon dioxide, nitrogen). Overall cylinder station consists of two rows of cylinders equal, one of these two grades be in working condition while the other shall be the primary alternative to the class when emptied Alostoanat.oicon automatically switch between grades through autoomatic switch the possibility of switching from row to row the other hand. It must be designed so that the station does not stem the tide of medical gas at the service station or maintenance.
May use liquefied oxygen tanks in large hospitals or when a large consumption rate. Oxygen tanks are insulated tanks containing thousands Turat of liquefied oxygen when evaporation produces oxygen gas multiplier hundreds of times the size of its size it is liquefied. These tanks are placed in special places and each tank there and from which you can fill the empty tin when its piping system,
Second: The compressed air supply station through the air compressors
Unlike other medical gases, which are supplied through the cylinder, the medical compressed air is usually Antiajh in the hospital itself and that is through the payment of external atmospheric air into the air compressors, which are linked to a network of pipes that supply the various medical departments air after treatment in order to comply with the air specifications Medical where the following conditions must be in the compressed medical air and the output of the station are available:
• oils ratio does not exceed 0.5 mg per cubic meter.
• dew degree of not less than 5 degrees down less unexpected degree of operating temperature.
• Carbon monoxide ratio does not exceed 5 ml per cubic meter.
• carbon dioxide ratio does not exceed 1 000 ml per cubic meter.
Third, the suction through suction pumps station
Suction station of three or more suction pumps consists, tank or more, two or more filters bacteria, a jar exchange or more in addition to the unit for the station control. It must be suction abroad exchange station away from the neighboring buildings and the direction of the wind away from neighboring buildings.
Distributed pipes for gas network
Piping system used for the transmission and distribution of medical gases from gas stations to the exits of the various sections, taking into account the following:
• pipes must bear the pressure equivalent to 1.2 of the maximum possible pressure.
• flexible connections may be used as part of the network so as to prevent transmission of vibration.
• You must reach your piping system grounded in hospital.
• must be the protection of piping system from damage that may result from the collision devices such as Alterolliat and dispute.
• must prove pipes pillars so as not bend or bows out.
• props must be made of corrosion resistant material.
• should not be used for any special props pipes other uses.
